Hadi Hajibeygi
Hadi is a professor of Geo-Energy Solid and Fluid Mechanics at Delft University of Technology. His research centers around advancing modeling and simulation sciences for processes in geological reservoirs – both experimental and computational, specially addressing multiscale heterogeneity and uncertainties across scales. Hadi holds a PhD with medal from ETH Zurich in Fluid Dynamics and was a Postdoc Scholar at Stanford University Energy Resources Engineering before joining TU Delft in 2013. The applications of his research include underground hydrogen storage science and technology, as well as carbon dioxide storage and well as geothermal energy exploitation.
Course Description:
The increasing demand for accurate and efficient simulation of multiphase flow, heat transfer and mechanics in subsurface formations motivates the development of advanced computational methods which are not only accurate but also amenable to uncertainty quantification. The non-linear, heterogeneous, uncertain, dynamic and coupled nature of the mathematical formulations make such developments challenging, yet possible if a multiscale methodology is properly devised for the components of the coupled system. Such multiscale methodologies allow for a physics-based algebraic dynamic multilevel description of the highly-resolved heterogeneous discrete equations in both space and time. At the same time, they allow for crossing up and down between resolutions, with systematic error reduction to any desired norm. This short course is offered to enable the attendees to get an in-depth knowledge and hands-on experience with multiscale simulation of multiphase flow in fractured reservoirs. While we develop our own python codes in the class for many of the topics, we will also introduce the Delft Advanced Reservoir Simulator (DARSim), which has many of the multiscale topics for 3D complex systems.
